A huge blast probably caused by the explosion of chemical materials killed at least 14 people and injured more than 700 yesterday at Iran’s biggest port, Bandar Abbas, Iranian state media reported.The explosion hit the Shahid Rajaee section of the port. Hossein Zafari, a spokesperson for Iran’s crisis management organisation, appeared to blame the explosion on poor storage of chemicals in containers at Shahid Rajaee.However, an Iranian government spokesperson said that although chemicals had likely caused the blast, it was not yet possible to determine the exact reason.Iran’s President Masoud Pezeshkian ordered an investigation of the incident and sent his minister of interior, who said efforts were still ongoing to extinguish the fire and prevent it from spreading to other areas.Located near the strategic Strait of Hormoz, Shahid Rajaee port is Iran’s biggest container hub, handling a majority of the country’s container goods.
